The filter scarf is a discreet yet a highly effective gasmask that ensures a good quality of breathing air, wherever you are. It has two functions – detect and protect. A small electronic sensor reacts to air pollutants and warns the wearer. The scarf itself is lined with a carbon filter that absorbs the hazardous substances in the air.

The inside is a bright fabric printed with fresh trees. One side of the scarf is dark and the other is bright. This makes the feeling that the air goes from dirty to clean. After a while the filter turns full and then it is possible to wash the scarf in the laundry and use it again.
